Plate Deflection Subject. A loaded circular plate will deflect and a hole in its centre will cause it to deflect still further. Whilst its predictability is not straightforward, this deflection and the consequent stresses can be determined within acceptable levels of accuracy if the maximum deflection is no more than 10% of its outside diameter and the material continues to obey Hooke's law.

The beam will fail, even though the bending stress in the wood is below the wood failure stress of 50 MPa since the maximum bending stress in the steel is over 150 MPa. If the beam was only wood, it would still fail since the maximum bending stress would be 75 MPa (calculations not shown) which is beyond the failure stress of 50 MPa.

Allowable Stress (Strength) The allowable stress or allowable strength is the maximum stress (tensile, compressive or bending) that is allowed to be applied on a structural material. The allowable stresses are generally defined by building codes, and for steel, and aluminum is a fraction of their yield stress (strength):
The failure mode of a primary stress. is gross defonnation progressing to rupture. Examples of a primary stress are circumferential stresses due to internal pressure & longitudinal bending stresses due to gravity. The basic characteristic of a secondary stress is that it is self- limiting. The stress will diminish with time and strain.
